I am trying to update to 5.6.1 and I am getting this error:
"There was an error unpacking your file. Perhaps you have not uploaded a valid zip file, or you do not have zip installed."

I had to create a php.ini file because I was getting the error about there not being enough space delegated to installing files... So my file just includes:

register_globals = On
safe_mode = Off
memory_limit = 64M

extension=php_zip.dll

Could someone give me a sample php.ini to use that will install zip, please? thanks!
